Simple explanations for plumbing problems

Plastic pipe from eaves – only when radiators are hot

Water level in central heating feed tank is too high when cold.

This can be caused by the float of the ball valve developing a leak. When its full of water it doesn’t float on top so the water level rises too high. The ball will just unscrew and can easily be replaced.

The valve will have some adjustment on it in the form of a sliding threaded nut that connects the ball to the arm of the valve. In some cases the water level is still too high at maximum adjustment. For an extra low water level the arm of the ball valve can be bent level.  Its a lot easier to do while the valve isn’t in the tank.
